I think that I have settled on  haworthia reinwardtii
f. kaffirdriftensis .

There seems to be some confusion as to whether it is a haworthia or a Haworthiopsis. The book of life likes Haworthiopsis but also says that it is in the family asphodelaceae which has been renamed to  xanthorrhoeaceae as far as I know, so I am going with Kew's assessment.

Can someone tell me what the "f." stands for in f. kaffirdriftensis?? I am seeing this type of notation frequently of late in succulent and cactus classification.

Thanks

From what i have learned, the "F." in certain species name descriptions is supposed to describe a particular form of a given species.. so, for example, the  f. kaffirdriftensis "form" of the standard species, Haworthia reinwardtii, could present something that makes it distinct from the standard form ( ie: leaves colored / arranged differently, flowers at a different time /season.. might be from an isolated population far removed from the "normal" range the species might be found.. etc) 

Another example would be something like Bursera microphylla.. many different forms of the species can be found spread across it's broad range.. Some forms have especially narrow leaves, others  wider/ longer in length.. or contain more or less leaflets / flowers per cluster. etc.  What had been long considered a specifically distinct form of this plant from the eastern Cape region of Baja was designated as it's own, new species last year.

Great, f. equals form. I wonder what makes form different from var or ssp

not always that easy to tell Haworthia reinhardtii from coarctata... below are some of H coarctata plants

So, according to Bayer, coarctata has wider leaves, smaller more rounded, less white tuberlces. The biggest difference is that leaf width of coarctata is almost twice the width of the stem, while reinhardtii is slightly larger (1.2 to 1), hence I will change my labels and the plant database at http://Selva.Cabal.mx to reflect the name h. coarctata for this one.

Thanks for the heads up
